To be precise:
- a Google+ page identity (not a personal profile)
- that was created for a regular Blogger blog
- in turn created, and now administers, a second blog.
The blog, called "Proof of Concept," has no purpose other than to illustrate how a G+ page can do any and every blog-related thing that a plain-vanilla blogging account can do.
Specifically, a properly constituted Google+ page can
- be anonymous or in the name of your blog or business or brand
- be a blog author and write posts
- be a blog administrator and moderate comments and change blog design and settings
- share blog posts on Google+
- leave Google+ comments on a blog that enables them
- leave regular (i.e., not G+) comments on a blog that enables them
- create and administer blogs
Proof of Concept could have its own G+ page, which could create another blog, which—but let's not get carried away.

For instance, a page can have multiple administrators and is not subject to Google's real-names policy.
And you do need at least one Google+ profile to administer the page.
But in terms of Blogger, it does everything a regular account can.
